s, it is one of the largest species in the world. Its length, at , is somewhat less than the great eared-nightjar, which is typically considered the largest species in the family, but the nacunda may actually weigh a bit more on average. Six specimens of nacunda nighthawk were found to average in body mass, with range of . Its very large size, large head, and pale body with highly contrasting black primaries make the nacunda nighthawk easy to identify. This species is noteworthy for its partially diurnal habits. Though a capable aerial forager, the nacunda nighthawk spends a considerable amount of time on the ground; it has notably long tarsi for a nightjar, and is more likely than other species to be seen standing on the ground, rather than resting on the surface.
